Project Description

i need to solve five task in reliability

The pilots of Green Airlines which flies the Boeing 797 exclusively are known for their “rough” landings. When the force of the landing exceeds the strength of a wheel strut, a fracture (failure) will occur. The strength of wheel strut is affected by number of landings, , and described as 650 exp([url removed, login to view]) psi. Measurements on the force of each landing have determined that the distribution is Weibull with a shape parameter of [url removed, login to view] and a scale parameter of 209 psi. Each aircraft averages 3 landings per day.

Answer the following questions:

1) Determine the time (in days) to initial inspection of the landing gear struts to insure no more than a 0.5% chance of a strut fracture (failure). Any fractured struts are then replaced and the inspection interval starts over. (8 marks)

2) If no fracture is found, the struts are inspected again after 60 days. What is the probability of detecting a fracture at the next inspection? (8 marks)
